The Lomatium grayi complex (Apiaceae) of the western United States: a taxonomic revision based on morphometric, essential oil composition, and larva-host coevolution studies

The Lomatium grayi complex is morphologically diverse across it range. The type species of this complex, Lomatium grayi s.s., has been found to not be a host of the larvae of Papilio indra, while the other three morphotypes are larval-hosts. A fifteen character, morphometric analysis was conducted on 390 herbarium specimens from throughout the range of this species. PCA, MANOVA, CDA, and Tukey tests revealed that the majority of the characters in this dataset were significantly different between four regional morphotypes. As a result of the morphometric analysis, the morphotypes are herein proposed as four species. Two new species are proposed for populations of L. grayi in the Pacific Northwest. Lomatium papilioniferum is proposed for plants in California, western Idaho, northern Nevada, Oregon, and Washington. Lomatium klickitatense is proposed for populations of robust plants from western Klickitat County, Washington, and northern Hood River County, Oregon. Lomatium grayi var. depauperatum is elevated to a species. This leaves no infraspecific taxa within L. grayi s.s. A presence/absence phenetic analysis of combined essential oil data was inconclusive regarding the composition of L. grayi s.s., which was found to be more similar to Lomatium klickitatense and Lomatium depauperatum than other species of Lomatium. Taxonomic treatments for each of the four species in this complex are provided. A key to these species and the multiple species that have been commonly mistaken for L. grayi is also included.

Piper jacquemontianum Kunth (Piperaceae) is a native species from Central America and the Caribbean lowlands. It is traditionally used as a medicine and condiment in several ethnic groups from the region. Essential oils of dry leaves were obtained from eight ecologically different sites of Guatemala, which were cultivated under similar conditions in the Pacific basin. The essential oil yields obtained by hydrodistillation varied with the site of collection (0.3-1.7%). The essential oil composition was determined by gas chromatography; E-nerolidol was the only compound common to all provenances, although in a wide range (5.7-73.8%), being the main component of four of them. In the oils from other provenances, the main components were linalool, terpinen-4-ol, spathulenol, and α-bisabolol. This is the first report on the variation of the essential oil composition of this species of different provenance cultivated under similar conditions, suggesting high variability in its composition, and demonstrating at least five groups of P. jacquemontianum according to the composition of its essential oil. In further agrotechnological research, selection of the most promising samples could generate unique cultivars which might produce the expected compound.

Antimicrobial And Antioxidant Activity

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.
